We study five-dimensional N=4 gauged supergravity coupled to three vector multiplets with SO(2)D× SO(3) gauge group. The gauged supergravity admits two supersymmetric AdS5 vacua. One of the vacua, at the origin of the scalar manifold ℝ+× SO(5,3)/SO(5)× SO(3), preserves N=4 supersymmetry and the full SO(2)D× SO(3) gauge symmetry. The second AdS5 vacuum is N=2 supersymmetric and invariant under SO(2)_\textrmdiag which is a diagonal subgroup of SO(2)D and SO(2)⊂ SO(3). By considering a truncation to SO(2)_\textrmdiag invariant scalars, we find a class of Janus solutions interpolating among these vacua. These solutions should be holographically dual to conformal interfaces within the dual N=1 and N=2 SCFTs in four dimensions. In addition, we also find examples of solutions describing RG-flow interfaces between N=1 and N=2 SCFTs on each side of the interfaces. All of the solutions could possibly be uplifted to eleven dimensions by a consistent truncation of M-theory on M3× S2× S1 with a 3-manifold M3.
